AND GENERA OF PLANTS. 257 



and as long or longer than its adnate tube. In the lower flowers the capsules are two-celled, and 

 the lobes of the calyx three or four, rarely five. Some plants occur entirely smooth; in others the 

 angles of the stem and the veins of the leaves beneath are pulvulous. 



*CAMPYLOCEIlA. 



Calyx in the upper flowers five-cleft, in the lower, apetalous ones unequally 

 three-cleft, with the adnate tube long, cylindric and curved; tube of the 

 perfect flowers, subterete and compressed. Corolla pelviform, five-cleft. 

 Stamens five, filaments very short, equal and smooth. Stigmas two, oval 

 and short. Capsule in the perfect flowers two-celled, subterete, usually 

 opening with one deciduous operculum. Capsule of the imperfect flowers 

 terete, one-celled, with a single parietal placenta, or a trifid, valvular dehis- 

 cence at length from the summit to the base, nearly as in Clintonia. Seeds 

 even, elliptic, compressed, contorted. An annual of Arkansas, with much 

 the habit of the preceding genus. Stems simple or branching from the base; 

 leaves alternate, lanceolate, nearly entire; flowers solitary, axillary. (The 

 name alludes to the curved, horn-like appearance of the lower capsules.) 



Campylocera leptocarpa; stem hirsute at the angles, leaves ciliate.

Hab. Arkansas; five to ten inches high. Except the upper surface of the leaves, covered with 

 a minute hirsute pubescence. Leaves lanceolate and linear-lanceolate, the radical ones slightly 

 crenulate. Calyx in the lower apetalous flowers cylindric and curved, with three ringent or un- 

 equal lobes, the capsule one-celled, with one of the three valves only placentiferous, and that 

 parietal, as in the rare examples in this order of Clintonia and Lisipoma. The perfect two-celled 

 capsules three quarters of an inch long, two-celled, linear and compressed, rounded at the sides, 

 somewhat narrower at the base and summit, usually opening with but one opercular valve. In 

 these flowers the five divisions of the calyx border become rigid and spreading, linear and acute. 

 Corolla blue, conspicuous, rather deeply and acutely five-cleft, wholly like that of Specukiria. 

 The affinities of this plant, indeed, appear to be in the perfect flowers to Specularia, and the im- 

 perfect ones, in the absence of the corolla, might be mistaken for those of Clintonia: the valves are 

 also almost equally as much contorted. The imperfect flowers appear a long time previous to 

 those which are corolliferous. ft. Fort Gibson, Arkansas. [Engelmann.']
